Why weeks make time visible

A year is easy to talk about and hard to feel. A week is small enough to remember: the meeting you kept, the dinner you postponed, the Saturday that disappeared into errands, the quiet hour you actually protected. This grid turns a 90-year life into 4,680 squares, so the scale becomes visible without turning it into a sermon. Filled squares are weeks that have passed since the birthday you enter. Empty squares are still ahead. The amber outline marks the week you are in now. It is not meant to be grim; it is meant to be concrete.

Use the life-expectancy field as a planning assumption, not a prediction. The grid itself stays at 90 years because that is the familiar Wait But Why shape, while the remaining-weeks statistic adjusts to the lifespan you choose. For exact calendar age in years, months, and days, use the age calculator. If you want a stranger angle on the same birthday, the age on other planets tool converts your elapsed Earth time into Mercury, Mars, and Neptune years. This page keeps the math deliberately simple: local calendar days, full elapsed weeks, and ordinary milestone dates you can put on a calendar. The point is not to optimize every square. It is to notice that they are real, limited, and still yours to spend.

See a 90-year life, one week at a time.
